PMIC for wearables

29 April 2015 Power Electronics / Power Management

ams introduced the AS3701, an integrated power management IC (PMIC) with an especially small footprint for use in wearables and other space-constrained devices. The IC, with a low quiescent current, implements multiple power regulation, power saving, battery charging, protection and startup functions in a chip-scale package (WL-CSP) measuring just 2 x 2 x 0,4 mm. Its multiple power rails include two 200 mA LDOs, a 500 mA step-down DC-DC converter and two 40 mA programmable current sinks. Many designs will use the I²C interface to enable configuration by a host processor or microcontroller, but the device also includes multi-purpose I/Os for wake-up/power-down inputs, PWM inputs and outputs, interrupts and control tasks when operating in standalone mode.
